The two tubular bannerstones pictured in Figure above A and B are examples of the most often observed style of Benton tube. Collectors often refer to this tubular bannerstone as a "Covered Wagon" style due to its similar shape profile to the Conestoga Wagon of pioneer days. This style Benton tube was most often made from mint-green claystone, that most likely had its geological origin in the Quachita Mountains of central Arkansas, and it was a favorite material used by Benton culture peoples for manufacturing both tubular and shuttle style bannerstones. This claystone often contained bands of a white material. The perforation, drilled through the long axis of tubular bannerstones, was most often parallel to these bands. Examples that exhibit bands that are perpendicular to the long axis of the bannerstone are rare. The "Covered Wagon" style bannerstone depicted in Figure IC is an example of this rare variant. The example depicted in Figure 1 B is made of a dark-brown claystone, found locally, that was often used to manufacture bannerstones. Higher developed examples of this style exhibit much more concavity of the top edge. However, both convex and straight top edge variants are known. The example depicted in Figure 1 D illustrates a slightly concave top edge with bilateral cane-drilled indentions. This variant with cane-drilled indentions is very rare. Also, solid-stick drilled indentions occur on some "Covered Wagon" style bannerstones. The example depicted in Figure 1 E was pictured earlier by both Knoblock and Lutz and it features bilateral solid-stick drilled indentions.
The example depicted in Figure 2 below is an example of a "Mississippi Crown" style Benton tube. This style is rectangular in shape with a well defined hump that is located in the middle of one side. The hump profile of highly developed examples resembles a three-prong crown. This style tube is only found in north Mississippi and most examples are made of mint-green claystone. Examples made of Limonite or a dark-brown claystone are known; cane drilled bilateral indentions occur on some examples of this style. The less developed examples are often made of Limonite and often exhibit cracking and sometimes exfoliation of the outer surface. Less developed examples are often found with caches of small preform biface blades made from Tuscaloosa gravel and small Benton biface points made from Tallahatta quartzite. The example illustrated in Figure 2 is a less developed style of a "Mississippi Crown" style banneerstone.
Another unique style Benton tubular bannerstone is depicted in Figure 2. This style Benton tube is called an "A-Frame" style by collectors. The geometric profile of highly developed examples are made of either a dark-brown claystone or Limonite. Most examples exhibit a fluted base with some having a purported shaft groove. Examples exhibiting a well defined paneling made by removal of the outer surface of each lateral side are known.
The rarest unique style of Benton tube is depicted in Figure 2. This unique Benton tubular bannerstone is called a "spool" style by collectors. Its geometric profile resembles a sewing machine thread spool. It is rounded in shape with the middle outer surface removed to create a paneling effect. Most examples have a fluted base and are made from mint-green claystone."Used by Permission of the Author"
